  • Run-in behavior between the spring and the piston ring can be determined.
  • Me stands for metal and, for example, tungsten, chromium, titanium, germanium or silicon can be used for this purpose.
  • aC: H: Me and the aC: H layer mentioned below are DLC coatings and provide comparatively low wear and good friction properties.
  • At least partially DLC is present, so that the good friction properties, especially under

  • the usually higher resistance to wear of the CrN layer compared to DLC can advantageously take effect from the beginning or when the outermost DLC layer has worn out.
  • the described multilayer coating also offers the advantage that significantly higher overall layer thicknesses can be realized than with conventional DLC layer systems. This is essentially due to the fact that at DLC
  • the helical compression spring is preferably made of steel, in particular CrSi or CrNi steel, wound substantially helically and accordingly has two spring ends, which meet due to the largely circular arrangement of the spring in the installation or operating state without a gap. This point is preferably radially opposite the joint of the piston ring. It should be noted that the coating according to the invention, for example, in the
